What sort of torque figures can you expect from the same standard engine but with diffrent chip and injectors only ...

1- Standard engine,T34 turbo .63 housing,rs500 i/c,Dark green injectors= ?

2-Standard engine,T34 turbo .63 housing,rs500 i/c,grey injectors = ?

exactly the same

 

How do you work that out

regards mark

 

how would you increase torque by merely having bigger injectors?the main factor would be that you could run more boost and fuel for it,but if everything except the injectors is the same youll get the same result!

 

How??? bigger injectors = more power/torque

Obviously you are not going to change the chip and injectors without setting it up.
Maybe i have not explained it well but i cant see where i have gone wrong,lets try again

1-same engine- same turbo-same rs500 i/c- grey injectors and appropiate chip running 31psi peak and 27 held = estimated torque figure???

2-same engine- same turbo-same rs500 i/c- dark green injectors and appropiate chip running 25psi peak and 21 held = estimated torque figure???

fuel is always the easy bit to add,, its the AIR that we need to pump more of to gain more power!

without an increase in boost, on the same spec engine, you will have the same power no matter what injectors/ecu or airfreshener you have

 

im putting 1600cc injectors in mine tomorrow then,, do you think i will gain BHP over my 660cc injectors?

 

Read what i have typed,i have just carried out this conversion and it has considerably more torque,its fairly obvious really... set up with greys and running 31psi and holding 27psi is going to make more power and torque than a set up with dark greens and running 24 psi and holding 21 psi,or am i missing something...i am trying to find out what is a good torque figure for both conversions,thats all.

Right your first choice running greys was similar to my old 3dr, that made 363bhp/ with the same torque @ 32 psi holding 28

 

but the bigger injectors DONT give you more torque,read my reply,you are simply able to produce more boost without it running lean!but you can only do this within the limits of the turbo.
and my old engine on greys and a .63 t34 ran 409lb/ft on scs engine dyno for info.

 

They do give you more power and torque then! For the record, my same engine,turbo,i/c etc

1- greys and chip made 376bhp and 390ft/lb torque

2- dark greens and chip made 329bhp and 331 lb/ft

so obviously does make a major difference,i just wanted to see what was a average figure for both set ups.

no youre missing the point,if you simply swap the injectors youll get nothing,its the extra air flow from the turbo that gives you more power!!the bigger injectors just allow you to use the extra air!!

 

ie if you got a non turbo car and just added bigger injectors youd probably lose power.but with a turbo car you can increase the amount of air so the extra fuel can compensate for this

 

Thats not what i said though I am definately not missing the point

Biggers injectors mean you can run more boost which is what'll give you more lbft


Its not that hard to grasp is it

 

It seems to be for some all i wanted was to compare torque figures on a greys setup to a greens setup using a t34 .63 thats the trouble on here sometimes,im sure 99% of people know what im asking,i mean,how many change to greys and appropiate chip and leave the settings and boost as it was with greens

regards mark

 

so boost levels have nothing to do with uncontrollable burning and egt's then?

 

I was not talking about that though I said a greens setup against a greys setup on the same engine,obviously setup and running at their optimum,what would the difference be in the torque figures

regards mark

 

i made 325ft/lb torque on greens on a 2.1zvh from karl

BUT he did say he could have made that easily 400ft/lb but i asked him not to because of the ancillaries

horses for courses

 

hilarious how someone asks a black and white question, then gets the answer he doesnt want...

then goes on to give the answer...


why the fook ask it in the first place if you know

 

i did give my figure,but wanted to get a idea of a good figure for those specs i have had 2 answers to my question for greys...363 and 409 lb/ft

Its hard work though

i think i can see both sides here!yes you r right that the bigger injectors gives more fuel thus if u have the turbo to give more air = more power,but on the other hand on a standard engine i can understand why some have said u might not get more power due to limitations on the engine i.e with c/r no matter how much u pump in a engine might only be able to handle 23psi of pressure?so it would not matter how much extra u pump in!if u get me????

 

Eh?! When did I go into EGT's

 

.............i know what you mean fella,but unless u explain the far end of a fart on this site,.....u end up with the above.... ..never had greys,or .63 but had greens and .48 and made 357bhp/340ftlbs.........23psi held

 

It appears that a standard cosworth engine with t34 .63 turbo,anything over 350 lb/ft on greens and 400 lb/ft on greys is a good figure Thanks for all the other technical replies

sorry i quoted the wrong part of your post , you wrote

"Biggers injectors mean you can run more boost which is what'll give you more lbft"
